REDONDO BEACH, Calif., Oct. 30, 2008 — Northrop Grumman Corporation (NYSE:NOC) has completed manufacturing and integrating a spacecraft engine that runs on the “green” or non-toxic propellants of liquid oxygen and liquid methane for possible use on NASA human exploration missions to the Moon, Mars and beyond.

The company’s TR408 second-generation, oxygen-methane 100 pound-force reaction control engine (RCE) was designed for the Propulsion and Cryogenics Advanced Development Project within NASA’s Exploration Technology Development Program, and features robust operation over widely variable propellant conditions. Propulsion systems using engines like the TR408 may have the potential to use green propellants that are produced from lunar or Martian soil.
